DC Comics has unveiled a trio of new heroes joining the world’s finest in Steve Orlando and Ivan Reis’s upcoming Justice League of America series: a series the company is hoping will be its most diverse roster of League members yet. UPDATE 2.15 PM EST: And now there’s a fourth member confirmed, Killer Frost!

Legends of Tomorrow is hitting in a big way—we saw the awesome trailer last week, and the current Arrow /Flash crossover is setting up this spin-off to those two shows. While some of the characters have appeared on TV already, some of the Legends are still strange and mysterious. Here’s our guide to who’s who!

With the announcement that the CW is expanding its superhero show roster with an Atom/Firestorm/Black Canary team-up show, it looks like we might finally be getting something Smallville tried (and ultimately failed) to do: Create the Justice League on television. But this time, it might actually work.

Guys. GUYS. I don't know how this is possible, but Arrow has revealed the high-tech A.T.O.M. armor that Brandon Routh will be wearing as Ray Palmer in future episodes, and... well, I don't know how to say this, but... it's kind of completely awesome.

Kurzgesagt has a neat new explainer: "How small is an atom?" I watched it. It does a great job at giving you an idea of how small atoms are and how they work. But it doesn't matter, because my brain just plainly refuses to believe any of this. Hulk head hurt. Hulk smash atoms. Oops, Hulk make nuclear detonation.

The producers of Arrow talk about their plans for more shows in that universe, and we get a sense for what Supergirl will be like as a show. Duncan Jones talks about the crazy special effects in Warcraft. Watch new teasers for Kingsmen: The Secret Service and The Walking Dead. Spoilers now!

Remember when Dell made Android tablets interesting again? Four months later, you can finally buy the Dell Venue 8 7000 tablet. While it's still listed as "coming soon" on Dell's website, Best Buy is now carrying the slate which wowed us with a beautiful screen, crazy camera, and ultra-thin chassis. It'll set you back…

Just a couple of months ago, Intel's new 4th generation processors helped laptops get a whole lot better. Now Intel's trying to work the same magic on mobile. Meet Bay Trail, a new flavor of chips designed specifically to make Windows 8 and Android tablets more awesome.

Ever gone for a long bike ride in unfamiliar territory? Probably used your phone's GPS to help navigate, right? Convenient. However, that also makes running out of juice more than just a small annoyance. Siva Cycle's Atom might just solve that, and a host of other battery issues for the tech-bound biker.

Lenovo probably did Windows 8 the best of anyone so far with the bendy, twisty Yoga. Now it's got the Thinkpad Tablet 2 and keyboard combo. If the Lenovo Yoga is a laptop that's sort of a tablet, this is the tablet that's sort of a laptop.

The Lenovo K900 is a big phone, yes, but it's a designy big phone. It's handsome, skinny, and slick like the finest smartphones ever made. We never thought we would be into a 5.5-inch phone until the K900's brushed metal back landed in our hands.

Windows 8 hardware sales are off to a slow start as shoppers scratch their heads over Microsoft's new operating system and flock to low-cost tablets instead. Could a souped-up netbook save the day? The latest hybrids powered by Intel Atom processors promise the best of both worlds: the versatility of a laptop combined…

We got hints from an early Geekbench result that the iPhone 5 was going to be flying. It seems that Apple's really has worked some magic, both with iOS 6 and its custom silicon, to make the iPhone 5 absolutely blazing at crunching Javascript. Browsing on the iPhone 5 is going to be lightning quick.

This isn't a wallpaper design from the seventies, or a close-up picture of the sun. Though it might look a little garish in orange, what you're actually looking at is the first ever recorded image of an atom's shadow.

How do you weigh an atom? To be honest, that's a question with plenty of problems which need answering, but one thing's certain: you need some accurate scales. Now, scientists have made a set that can measure the smallest unit of mass, the yoctogram—which is less than the mass of a single proton.
